They deactivated my lines and due to this reason and I had to purchase new sim cards in order for my lines to be activate again which cost R315.00 out of my pocket for their negligence. To add more frustration they went and debited my account again with R933.48 dated 03/02/2016 which obviously came back as unpaid because I did not cater for this debit as I was not made aware there will be a fee of R933.48 as well as R115.00 unpaid on my cheque account....again I had to bare the costs for Vodacom's mess up. I requested to have the contract cancelled and was told by the agent that I cannot cancel or else I will incur penalty fees and can only cancel in June because of the reactivation of my lines done.
